Iron(III) chloride-catalyzed effective allylation reactions of aldehydes with allyltrimethylsilane

Iron(III) chloride-catalyzed allylation reactions of a variety of aldehydes with allyltrimethylsilane proceeded efficiently and smoothly to afford the corresponding homoallyl alcohols in high to excellent yields. This novel method could be suitable especially for the allylation of sterically hindered aliphatic aldehydes.
